We used the fecal analysis method to document the diet composition of flying foxes and analyzed 107 samples collected from roosting sites. We identified 8 plant species in the diet of flying fox belonging to three families of plants including Moraceae (78.72%), Rosaceae (12.80%), and Myrtaceae (11.34%). We recovered two species belonging to the family Moraceae in the diet of flying fox including Ficus carica (46.73%, n=50), Morus nigra (29.91%, n=32). Similarly, four species of family Rosaceae were consumed including Prunus armeniaca (4.67%, n=5), Eriobotrya japonica (3.74%, n=4), Pyrus pashia (2.80%, n=3) and Prunus persica (0.93%, n=1). Whereas two species of family myrtaceae including Syzygium Cumini (9.35%, n=10) Psidium guajava (1.87%, n=2) and were consumed by flying fox. Results from this study show that Indian flying fox mainly consumes Morus nigra and Ficus carica carica. More detailed studies should be conducted to investigate seasonal variation in diet composition of flying foxes, assess local perception towards bats and economic losses faced by local people as a result of flying foxes raiding on the orchids in the study area. * Corresponding Author: Faraz Akrim [email protected] 1 Basharat et al. Int. J. Biosci. 2021 Introduction giganteus is 8ft from ground level and they also feed Bats (Mammalia: Chiroptera) are distributed all over on the leaves of plant species (Sudhakaran and Doss, the world excluding; Antarctica, the Arctic, and 2012). The home range of flying foxes covers several islands (Hutson and Mickleburgh, 2001). hundreds of square kilometers of area and therefore Indian flying foxes (Pteropus giganteus) are fruit- these megabats can contribute as “Umbrella” species eating bats that belong to the order Chiroptera and to other species which share a common habitat with suborder Megachiroptera (Brunnich, 1782). The order them (Suter et al., 2002). The Indian flying foxes are Chiroptera is further divided into two suborders, the the old-world fruit bats that play a key role in the Megachiroptera with 186 species and the continuity of 114 species of plants all over the world Microchiroptera with 834 species. Suborder (Mickleburgh et al., 1992). However, some authors Megachiroptera comprises one family while the suggest that 300 plant species in the old world suborder Microchiroptera comprises 17 families. depend on fruit bats for their survival (Marshall, Indian flying fox is one of the world’s largest bat and 1983, Fujita and Tuttle, 1991). The most preferred it is distributed in India, Sri Lanka, Pakistan, roosting tree by Pteropus giganteus is Ficus but they Bangladesh, Nepal, and Burma (Simmons, 2005). In also prefer to roost on Tasmanian blue gum or Pakistan, pteropodids consist of three genera and four Southern blue gum, mango, and Tamarind (Venda, species which includes the Indian flying fox (Pteropus 2003). giganteus), the short-nosed fruit bat (Cynopterus sphinx), the Egyptian fruit bat (Rousettus Pteropus giganteus is hunted for its body fats by aegyptiacus), and the fulvous fruit bat (Rousettus native homeopaths as they use it to make medicine leschenaultia) (Roberts, 1997, Mahmood-ul-Hassan for painful joints and they are not given any et al., 2009). Indian flying foxes in Pakistan have protection by the law in Pakistan (Roberts, 1997). In been reported from Islamabad, Punjab, and Sindh many regions of the world, bats are facing a high risk (Eates, 1968, Roberts, 1991, Bates and Harrison, of endangerment (Racey and Entwistle, 2003). 1997). In Pakistan, the correct number of taxa of According to (Walker and Molur, 2003) one species chiropterans is still a matter of debate (Bates and of bat is endangered, four species are vulnerable, nine Harrison, 1997, Roberts, 1997, Walker and Molur, species are threatened, eighteen species are the least 2003, Wilson and Reeder, 2005). concern, seven species are data deficient, and one species is not evaluated in Pakistan. According to the The pteropodids are generally frugivorous and rarely IUCN Red List of Threatened Species, Indian flying insectivorous while other species of bats are entirely foxes are classified as the least concerned (Molur et insectivorous (Hill and Smith, 1986). For the source al., 2008) but their population is declining as a result of food, about 29% of bats rely on plants completely of habitat loss and hunting (Venkatesan, 2007). or incompletely (Fleming, 1982). Bats are long live Specifically, in Southeast Asia, the large Indian flying mammals (Wilkinson and South, 2002, Munshi- foxes are one of the most threatened subgroups of South and Wilkinson, 2010) and they reproduce at a bats (Mildenstein, 2002). Flying foxes have been low rate (Barclay and Harder, 2003). Bats have placed in the fourth schedule of the Punjab Wildlife various foraging habits, community acts, reproducing (Protection, Preservation, Conservation, and scenarios, and roosting modes (Jones et al., 2009). Management) Act 1974, which allows hunting of the Dietary resources are the most essential limiting Indian flying foxes in Pakistan (Mahmood-ul-Hassan resources for wildlife including bats (Findley, 1993). et al., 2010). The major causes leading to the When the sun sets, the bats depart from their roosts population decline of flying foxes are their large size, after 20 minutes, and their extremely large groups are colonial roosting habits, and large feeding areas separated into small groups for feeding purposes which make them susceptible to hunting and habitat (Neuweiler, 1969). The foraging height of Pteropus loss (Mildenstein, 2002). 2 Basharat et al. Int. J. Biosci. 2021 The conservation of flying foxes is vital as these Kashmir hill fox (Vulpes vulpes grifithii), (Akrim et Megachiropterains are vital for forest renewal al., 2017, Akrim et al., 2018, Akrim et al., 2018, processes and also play a significant role in Akrim et al., 2019, Akrim et al., 2019, Akrim et al., pollination and seed dispersal. There is a paucity of 2021). scientific studies on the ecology of order Chiroptera (Amori and Gippoliti, 2000). Very few studies have As far as the flora of District Kotli is concerned 463 been conducted in Pakistan and vital ecological data plant species belonging to 306 genera and 93 families required for the conservation of flying foxes are have been reported from the area. The most dominant lacking in the country, therefore, the current study families are Poaceae (54 spp.), Leguminosae (39 was designed to investigate the diet composition of spp.), Compositae (33 spp.), Lamiaceae (23 spp.), and flying foxes in district Kotli Azad Jammu and Rosaceae (22 spp.), whereas the leading genera were Kashmir, Pakistan. Ficus (8 spp.), Ipomoea, Cyperus, Euphorbia and Solanum (6 spp. each) (Khan et al., 2015). Materials and methods Study area Study design This study was conducted in district Kotli (33º 20’ to The field surveys of the study area were conducted 33 º 40’N and 73 º 6’ to 74 º 7’ E) Azad Jammu and during summer 2018 to 2019 for the collection of Kashmir, Pakistan during 2018 -2019. The average fecal pellets of Indian flying foxes. Samples were elevation of the study area is ranging from 500m to collected in the morning hours from 9 AM to 12 PM 2000 m above mean sea level. The average rainfall is when the flying foxes were at roosting sites. 1146.08mm and the months of August and July receive maximum precipitation of about (218.82mm Collection of fecal samples and 236.38mm respectively). The total area of this Samples were collected in zip bags directly below district is 1862 km2. District Kotli consists of six from the roosting sites as they fall on solid paved tehsils including Kotli, Fatehpur Nikyal, Sehnsa, surfaces (Hodgkison et al., 2003). Khuiratta, Charchoi, and Dulya Jatan. District Rawalpindi is located on its western side, on its The samples were collected randomly from the colony northern side district Poonch is located on its of flying foxes (Parry-Jones and Augee, 2001). After southern side Mirpur district is located and on the the proper placements of droppings in the zip bags, eastern side, Indian occupied Kashmir is located these fecal pellets were brought to the lab for analysis. (Amjad et al., 2016). For each fecal pellet data related to the site of collection, global positioning system (GPS) location, District Kotli Azad Jammu has a vast diversity of both and elevation were recorded. flora and fauna. There are two national parks located in district Kotli including Pir Lasura National Park Identification and Mahasheer National Park. Most studies have Fecal samples of bats were washed under running tap been conducted in Pir Lasura National Park, the water, by using a strainer to separate undigested food major wildlife species reported from the park include; items.
